Automatic Flow Limiting ValvesAutomatic Flow Limiting Valves do not require any additional balancing as do Manual Balancing Valves, therefore they reduce labor costs from not having to balance and rebalance the valves.

Isolator R, Isolator Y and K valves are available with a wide range of flows and PSID ranges, and are the perfect choice for tight spaces. These valves offer easily accessible flow control cartridges, accessible without breaking piping connections, so exchange of the cartridge for flow changes can be made as required. Isolator and K valves are the perfect choice for terminal boxes, VAV boxes, fan coil units, heat pump installations, and base board/in-cabinets.

Recommended Applications:• For Baseboards/In-Cabinets and Terminals: Smaller valves like the Isolator R or Isolator Y, and K Valves. Sizes 1/2″ – 3″

• For Air Handling Units: Larger Isolator R, Uni-Flange, and Wafers offer precise control for larger applications. Sizes 1-1/2″ – 6″

• For Chillers, Towers & Pumps: For higher flow applications use Wafers, Steel Flange, Grooved End or Weld End with multiple cartridges. Sizes 3″ – 24″

The Griswold Controls Automatic Flow Limiting Valve is used in many different applications, mostly in the HVAC industry to maintain balance in a HVAC System. The stainless steel flow limiting cartridge has a spring loaded cup that dynamically absorbs pressure fluctuations resulting from changing system conditions due to varying heating/cooling loads. These fluctuations in pressure, within a given pressure differential control range, do not change the flow through the valve, therefore the flow is controlled to within +/- 5% of the designed flow.

Manual Balance Valves

QuickDisc™ and QuickSet® Manual Balance Valves & Metering Stations

The QuickDisc™ and QuickSet® are manual balance valves that include venturi inserts for flow measurement and isolation valves with memory stops for flow setting. The venturis are precisely machined to attain ±1% accuracy throughout its range. The venturi produces a high pressure signal for flow adjustment, while creating very low permanent pressure loss, thereby minimizing pump head requirements and maximizing system efficiency.

QuickDiscTM Flanged End QuickSet®

Flanged End Metering StationQuickSet®

Manual Balance ValvesThe QuickDisc™ valve uses a ceramic disc to set the flowrate and the QuickSet® valves use a ball (1/2”-2”) or a butterfly (2-1/2”-20”) valve to set the valve flowrate. Both valves have built-in straight runs before the venturi. This design feature allows the valves to be installed after an elbow, temperature control or other valves without affecting flow measurement or control. Pitot Tube and Venturi metering stations require 4-10 diameters of straight pipe entry for accurate measurement. Many retrofit jobs don’t have 4-10 diameters of space, so accurate measurement is frequently compromised. Griswold Controls’ engineers studied “Disturbed Flow Measurement” and developed a patented Piezo Ring and dual chamber design, enabling accurate measurement in the smallest footprint. Now engineers can specify to ±1% accuracy and locate the valve with less than four pipe diameters entry piping, or adjacent to an elbow or temperature control. Whether a new or retrofit installation, these valves require only simple and direct piping, saving valuable equipment space and field labor and ensuring quality comfort conditioning and lowering operating costs for owners.

Griswold Controls also offers the venturi in a Metering Station that can be used for flow measurement. The Metering Stations are available with an electronic output signal (transducer) from the measuring station. This makes it easy and convenient to integrate the valve into a building’s energy management computer system and accurately measure flow at all times.

Recommended Applications:• For Baseboards/In-Cabinets and Terminals: Smaller valves like the QuickDiscTM or the Brass QuickSet® for balancing or Brass Metering Station for flow measurement. Sizes 1/2″ – 2″ • For Air Handling Units, Chillers, Towers & Pumps: Larger QuickSet® in Flanged, Weld or Grooved End style or Metering Station for flow measurement. Sizes 2-1/2″ – 20″

2-Way & 3-Way Actuated Ball Valves

Unimizer® 2-Way & 3-Way Actuated Ball Valves

Griswold Controls’ Unimizer® valves achieve true equal percentage flow from the patented parabolic shape of the Optimizer. The valves include the patented low torque seals allowing the same 35 in-lb actuator to be used on 1/2" to 3" valve. The valves also feature the universal mounting plate which allows the valve to be installed with your choice of actuator. And finally, the Unimizer valves feature the patented repairable Next Generation stem which allows for stem repair or replacement without removing the valve. This extends the life of the valve well beyond traditional actuated valves on the market.

3-Way Unimizer® 3-Way FlangedUnimizer®

2-Way Unimizer®

2-Way & 3-Way Actuated Ball ValvesThe Unimizer® eliminates inaccuracy in ball valves. This is made possible with the technology of the Griswold parabolic flow OPTIMIZER®, a device inserted into the ball to achieve Equal Percentage Control Characteristics.

Why choose a ball valve over a globe valve? With the Unimizer® you can achieve the low Cv ratings of a globe valve at the low price of a ball valve. You can get the added benefit of higher close off pressure.

Many manufacturers settle for providing non-equal percentage control to the coil, or they achieve equal percentage control by using a costly, custom programmed actuator. Griswold Controls’ Unimizer® achieve true equal percentage flow from the parabolic shape of the Optimizers® located at each port, thereby allowing the use of any standard, low cost actuator.

Recommended Applications:• For Baseboards/In-Cabinets and Terminals: Smaller valves like the Brass Unimizer. Sizes 1/2″ – 3″ • For Heat Pumps: Smaller valve like the Brass Unimizer with a quick acting 35 second actuator. Sizes 1/2”-2”. • For Air Handling Units, Chillers, Towers & Pumps: Larger Flanged Unimizer. Sizes 2-1/2″ – 6″

Equal movements of the valve stem at any point of the flow range change the existing flow an equal percentage regardless of the existing flow. As you can see in the graph, our valve (red curve) mirrors the equal percentage characteristic of the coil (green curve), resulting in linear heat transfer. Unlike any other 3-Way valve on the market, the total flow or the sum of bypass flow and straight through flow (yellow line) never exceeds the maximum flow rating which saves pump energy since the system is never overflowing.

Pressure Independent Control ValvesSizes: 1/2″ – 6″

Griswold Controls’ PIC-V®, MVP®, Pinnacle and PIM valves are Pressure Independent Control Valves.

Pressure independent (PI) valves can help reduce energy costs and increase occupant comfort. PI control valves are designed to replace the conventional 2 way control valve and balancing valve pair, installed at heating and cooling coils in buildings. To obtain the most efficient and optimal results in a system, only the necessary amount, no more and no less, of chilled or heated water must be delivered to the heating and cooling coils at all times. Traditional control valves allow for over flow and under flow to coils which means excess water is pumped to compensate for their inaccuracy.

Pinnacle

MVP®

PIM-A

PIC-V®

Pressure Independent Control ValvesThe actuators in traditional valves have to cycle more often to compensate for pressure changes in the system that impact the flow. By precisely controlling the flow of water to each coil, the valve enables energy savings, increases available plant capacity, minimizes capital expenses necessary to acquire additional capacity, and simplifies system design and control.

Every year billions of dollars are wasted due to the weaknesses in HVAC heating and cooling systems. If heating and cooling systems do not consistently operate at their designed temperature differential, costly energy waste occurs. This unnecessary expense can be eliminated by using Griswold Controls’ pressure independent valves.

Recommended Applications:• For Baseboards/In-Cabinets and Terminals: Smaller valves like the Pinnacle or PIC-V. Sizes 1/2″ – 3″

• For Heat Pumps: Smaller valve like the PIC-V with a quick acting 35 second actuator.Sizes 1/2”-3”.

Flow changes as pressure and/or open area changes. In a PI valve if you maintain a constant pressure (P) drop AND a constant area (A) the flow (Q) remains unchanged until the actuator changes the open area. Q= A*√ΔPThe actuator rotation moves the horizontal fixed flow line up or down to provide temperature control modulation. Simultaneously, flow control is maintained along the horizontal portion of the graph within the minimum & maximum differential pressure limits when the pressure in the system changes.

Combination Actuated Ball Valve and Flow Limiting Valve

Automizer® and Balance Zone Automatic Flow Limiting & Temperature Control

Griswold Controls has combined the equal percentage control of the Optimizer® insert with the precision of the Griswold Stainless Steel Flow Limiting Cartridge in the Automizer valve. The Griswold Controls Flow Cartridge limits flow from exceeding coil’s specification, while the Optimizer® creates a smooth, responsive flow curve when the valve is actuated.

Automizer®

Combination Actuated Ball Valve and Flow Limiting ValveMost coils have an actuated control valve and a balancing or flow limiting valve. Two valves means two manufacturers and two distributors. Griswold Controls provides a single source for both valves, for less hassles and less headaches. Griswold Controls’ Automizer® valves combine all the patented features of the Unimizer valve with a flow limiting cartridge. Besides the equal percentage Optimizer it also includes the patented low torque seals allowing the same 35 in-lb actuator to be used on 1/2" to 2" valve. The valves also feature the universal mounting plate which allows the valve to be installed with your choice of actuator. And finally, the Automizer valves feature the patented repairable Next Generation stem which allows for stem repair or replacement without removing the valve. This extends the life of the valve well beyond traditional actuated valves on the market. And for an added feature, the Automizer® has an integrated isolation ball valve so it is the entire return side of the coil in one valve. The Balance Zone also incorporates a flow limiting cartridge with actuated control. Its compact size makes it ideal for all zone valve applications but since it includes flow limiting cartridge it extends actuator life since hunting is eliminated. Unlike most zone valves on the market, the Balance Zone has a high close off pressure. Ideally, a control valve settles into position once a heating or cooling setpoint is reached and doesn’t move again until there is a change in the room’s load requirement. Pressure changes in the system however, impact the room’s heating or cooling so a valve has to open or close to compensate. When this happens over and over it is called hunting and the constant actuation shortens the life of the actuator. Both the Automizer and Balance Zone Valves limit the flow to the control valve’s actuated set point so that the actuator doesn’t have to move until there is a load change in the room.

Recommended Applications:• For Baseboards/In-Cabinets and Terminals: Smaller valves like the Balance Zone or Automizer. Sizes 1/2″ – 2″

• For Heat Pumps: Smaller valve like the Automizer with a quick acting 35 second actuator.Sizes 1/2” – 3”.

Piping Components and Accessories

Isolator U, Isolator B, Isolator S, Y-Strainers, Flange Accessories

Valves are never installed alone. Automatic Flow Limiting valves, Manual Balance Valves and Actuated Valves are all installed in HVAC systems with other valves and accessories. For example most coil manufacturers and control valve manufacturers recommend strainers are installed before their equipment. Most building owners require that isolation valves are installed on mains and branches to make maintenance on equipment easier. Instead of sourcing all the accessory valves from different suppliers, Griswold Controls has sourced piping components and accessories to meet all your needs.
